So, this has me stumped (which isn't hard)
Stopped got fuel and I thought it cranked a little slow. Got on the road and the little lightning bolt light turned on as well as the battery light but kept running. Got up to highway speed and battery light went out, but lightning bolt stayed blinking until I got home.
Got home, turned off the jeep, then tried starting it up which it did. Tried again 15 seconds later and nothing. Pulled the codes and got a 560 code which from what I have read is a voltage code. My thought was the battery.
Pulled the battery and put it on the charger and was fairly close to dead. Let it charge all the way up, installed and nothing. Okay, bad battery
Bought a new 850 cca battery installed and still nothing. No clicks no nothing...
What is the best way to chase this down? I have mediocre skills, but given time I think i can do most anything with instructions. Thanks for the help!!

Make sure the battery connections are clean and tight.
The negative battery cable going to chassis must be clean and tight both ends.
The grounding strap grounding the engine to chassis must be clean and tight both ends.
Check connections on Starter Solenoid/Starter Motor are clean and tight.
Check if it cranks when in "Neutral" instead of "Park"
Check fuse #8 (40 A) in the Relay/Fuse Box (Power Distribution Center..PDC) under the hood is not blown. Also check fuse #28 (15 A) in the PDC.
Swap over the Starter Relay in PDC with an identical one nearby...do likewise with the ASD Relay.
Make sure the Jeep is in Park or Neutral so you do not run anybody over.
Remove the Starter Relay and identify the Female pins 30 and 87 inside the Relay Socket.
Briefly jumper these pins 30 and 87 together inside the Relay Socket...engine should turn over and if ignition is turned ON may start and you can run like this for a while.
This above procedure bypasses the ignition switch, the Ignition Pin Actuator Assembly, the Starter Relay and the Park/Neutral Sensor inside the transmission (Range Sensor).
Then to see if the Actuator Pin Assembly....rotates the ignition switch to Start when ignition key is turned to Start.....is broken..which is a common problem...do the following. Re-insert Starter Relay.
Obtain a Multimeter if you do not already have one....a cheap Chinese Digital meter is accurate enough for your purposes.
Check Starter Relay Pin 86 gets +12 volts when ignition switch is turned to Start...you can measure this +12 volts on both sides of fuse #28. If +12 Volts is not there then the ignition switch or the Actuator Pin Assembly is faulty....more on this later.
If +12 Volts is there...check if Pin 85 on the Starter Relay...Dark Green/Orange wire...goes down to ground with respect to the Positive Terminal on the battery....failure to do so means there is a problem on the Park/Neutral interlock inside the Transmission. You can temporary ground this Dark Green/Orange wire to see if it then turns over...make sure you are in Park/Neutral. If it does crank then the Range Sensor inside the transmission is possibly faulty or there is a wiring problem or bad connection at the ECM or TCM.
With battery disconnected....unplug/replug the connections on the ECM/TCM a few times in case of a bad connection.
To get back to the Actuator Pin Assembly...there are lots of posts on this issue to search on but basically:
Remove the plastic covers over the steering column...two Female Torx screws.
Remove the Ignition Switch from the Actuator Pin Assembly....smaller female Torx screw. This will be a Security Screw ie. it requires a Male Torx Bit with a hole down its center to remove the screw.
When you pull the ignition switch from the actuator pin...see if bits of plastic/metal fall off. This means the Actuator Pin Assembly tip has broken and you need to buy a new assembly at Dorman or other suppliers...Dealers do not carry it...see the Post below by
Dgideon Help, Stranded etc. about where to get this Actuator Pin Assm!
In the meantime you can turn the ignition key using a small flat screwdriver...if ignition key is inside its normal slot to Enable SKIS and to disengage steering lock...it should start and run like this.
Download the 2006 KJ Service Manual here...includes Wiring Diagrams:
http://www.colorado4wheel.com/manuals/Jeep/KJBear in mind that the LHD 2006 CRD has a known problem where the wire harness goes
behind the Fuel Filter Head Mounting Bracket and can get clamped to chassis which causes wires to chafe to chassis...if you do not find the problem with the above procedures then remove this bracket and check for damaged wires behind it!
